Biostock, are there more western women with Alzheimers because they live longer than men and chances of getting Alzheimers increases as you age? Have you, or the papers you cite, accounted for this?
In those 3rd world countries you cited (India, Cambodia, etc), is the incidence of Alzheimers the same between women and men, or do women experience it in greater numbers just like in the West?
Are there less numbers of Alzheimers in the 3rd world because life expectancy is lower, so they die of other things before they even have a chance of developing diseases of old age (Alzheimers, Parkinsons, etc)?
